Whitmore and Binyon Fixed Engine

I came across this engine through the good offices of a friend who knowing my interest in unusual engines let me have a copy of an engraving he had.

The engine was designed by Whitmore and Sons of Wickham Market, Suffolk, and was exhibited at the International Exhibition at South Kensington in 1862, (not to be confused with the Great Exhibition of 1851), where it gained an exhibition prize medal. The company in 1868 changed its name to Whitmore and Binyon. The company was founded by Nathaniel Whitmore in 1780 as a smithy for hand tools and agricultural machinery.

The main purpose of the unusual design was to drive direct by belt the vertical spindles of the old style flour mills. The engine engraving shows two pulley wheels but an engraving of the mill shows the engine driving three stones.

The base of the engine is a great cast iron drum within which is the flywheel, four Corinthian columns support an entablature which carries the upper bearing. An additional bearing above the pulley wheels was bolted to the mill framework. This is not shown on the model.

The flywheel is 215mm (8 ½") diameter and machinable on most model engineers lathes such as the Myford ML7 series. The flywheel is supplied as an iron casting and the cylinder is a gunmetal casting. Due to the shape of the base it has not been possible to produce it as a casting so it is made up from a series of laser cut laminations. These have most of the holes already formed so it is quite simple to bolt it together with a few spacers to for a rigid construction. The pulleys due to their slim design are also laser cut fabrications.

The drive to the crankshaft is by horizontal steeple motion which makes for a fascinating engine to watch when in motion.

The design is currently serialized in Engineering In Miniature.
